just in case anyone checks this thread, we had to get from Dover port to Ashford international for our eurostar train to france.
We used Britannia Coaches from the port (from the disney magic) to ashford international station.
They were fantastic and i highly recommend their service.
The driver was on time, courteous and an excellent driver.
In addition, they have an app that lets you know exactly where the driver is from about 2 hours before your pick up, so there's no doubt that he's on his way.
Definitely the company to go with if you want a driver to pick you up at the port and take you to ashford international.
We were a group of 9 people, so i booked their 16 person luxury coach.
Again, highly recommended. I would most definitely use their services again!
